Alligator Snappers
 

In an ongoing, lifelong effort to catch and hold an Alligator Snapper...I thought I would ask where is my best bet to find one around the St Louis Area...seeing I just moved down here a little while ago.
I have raised common snappers from eggs but not Alli's. Also 3-toed boxes from egg.
Mississippi river I would guess...but futher south I also assume??
Anyone ever catch one in the Marimac or Missouri rivers??
Thanks for any help you can give me.
Regards,
Dave
